    first plot your points on a graph.
    Then connect them.

    Just choose any three x values and work out the corresponding y values

    x = 0 and x = 1 are usually good choices

    I'd go with x = 3 for the third

    Technically the third one is not needed to draw the line but it is useful to do as it checks your first two. If all three points aren't on a line then you have made a mistake
